tenko is seen marching around the girls in a protective manner (like circling around them to prevent any male going near)

hajime (thinking to himself): 'uh.. is she okay..? She's been doing that for a while now..'

Nagito: "I don't really know why she's doing that.."

chiaki (glances at tenko): "zz.. hm.. I don't really mind her to be honest.."
